Question

Let A and B be two sets such that n(
AB) = 6. If three dements of AxB are (3,2),(7,5),(8,5), then A=
A) {3,7,8)
B) 2,5
C) (2,5,7
D) {7,8​

Answer 1

Step-by-step explanation:

a={3,7,8}.

this is the right answer

Answer 2

Given; n(AB) = 6. If three elements of AxB are (3,2),(7,5),(8,5)

To Find; A

Solution; It is given that n(AB) = 6. If three elements of AxB are (3,2),(7,5),(8,5),

Number of elements in =6

three elements ts of AxB are (3,2),(7,5),(8,5),

Since it's AB hence the first elements should be of A so A is A) {3,7,8)

Hence option a is correct
